Liqui-Cel® Membrane Contactors are widely used in the soft drink and brewing industries to Control dissolved gasses
Gas control is an important concern in the beverage industry. Oxygen in the water can oxidize flavor components and shorten the shelf life of the product. Carbon dioxide can also have an impact on taste and pH of the product. Liqui-Cel Membrane Contactors utilize a hydrophobic polypropylene membrane to remove dissolved gasses from water. Water flows on one side of the membrane and a vacuum or strip gas is passed on the other side of the membrane. By controlling the pressures of gasses in contact with the water, a highly efficient method for gas control can be achieved. ...view middle of the document...
Oxygen negatively impacts the taste and the shelf life of these products. Deoxygenation of water used to reconstitute fruit juices • Water blended with concentrated fruit juice should also be oxygen free. Oxygen will shorten shelf life and oxidize some of the flavor components.
CO2 Control of Beer • Adjust carbonation level on beer. Sometimes natural fermentation does not create enough CO2 for the end product which impacts taste and the head of a beer. On the same note, removal of excess CO2 in over-carbonated beer is also an easy process with Membrane Contactors.
Nitrogenation of Beer • There is a niche market for stout beer where N2 is added to beer to improve the foam head on top of the beer. Deoxygenation of Beer • Removal of oxygen picked up in beer during transfer. CO2 scrubbing • The CO2 is scrubbed with water to remove contaminants from the fermentation process (phenols, alcohol and other organics). Scrub water should be deoxygenated prior to scrubbing to prevent oxygen from contaminating CO2. H2S removal • Well water may contain H2S and this must be removed or it will negatively impact the flavor of the final product. Membrane Contactors are used in any part of the beverage process where gasses need to be removed, added or controlled to a specific level.
Some of the features and benefits that the membrane systems offer are:
Liqui-Cel® Membrane Contactors are available in a wide variety of sizes to meet the needs of many applications. For the beverage market, all components of the Liqui-Cel Extra Flow Membrane Contactor, when used in accordance with recommendations given in our product literature for treatment of processing water, alcoholic and non-alcoholic beverages, and aqueous, acid and non-acid food products at and below ambient temperatures, are in compliance with all relevant FDA regulations as specified in Title 21 of the Code of Federal Regulations.
